We study information diffusion in a large organization through a field experiment at the World Bank. We focus on transmission of scientific evidence on the impacts of generative AI by experimentally varying whether research findings are shared with senior or junior staff, and varying beliefs about peer adoption and evidence credibility. Providing evidence to senior staff significantly increases transmission and diffusion as measured by engagement with study materials and colleagues' recall of study details. In contrast, changing beliefs about peer adoption or credibility has no detectable effects. The results highlight the importance of organizational hierarchy in shaping informal information flows.
